1939-99-7, name is Phenylmethanesulfonyl chloride, belongs to chlorides-buliding-blocks compound, is considered to be a conventional heterocyclic compound, which is widely used in drug synthesis. The chemical synthesis route is as follows. HPLC of Formula: C7H7ClO2S
A solution of phenylmethanesulfonyl chloride (2.19 g, 10 mmol) was added into a suspension of 3-bromopropan-1-amine hydrobromide (2.19 g, 10 mmol) and Et3N (2.02 g, 20 mmol) in THF (50 mL) at 0 C. The mixture was stirred at 0 C for 5 mi TLC confirmed the completion of reaction. Solid was filtered out with suction, and the filtrate was concentrated to provide compound N-(3-bromopropyl)(phenyl)methanesulfonamide (2.7 g, quant.) as a pale yellow solid which was used in the next step without further purification. ?H NMR (300 MHz, CDC13) oe 7.40 (m, 5H), 4.48 (m, 1H), 4.27 (s, 2H), 3.41 (t, J = 6.6 Hz, 2H), 3.16 (q, 2H), 2.01 (m, 2H). LCMS (ESI), mlz, 314 and 316 [M+Na], Br pattern found.
The synthetic route of 1939-99-7 has been constantly updated, and we look forward to future research findings.
